[arch][arm64] Fix and improve fault logging The fault code (bits 5:0 of ESR) was only printed if ISV was set, however ISV indicates whether the instruction syndrome (bits 23:14) is valid. Parse and print fault code for data and instruction faults. Parse and print instruction syndrome when ISV is set. For data faults say whather the error occurred reading or writing. Use more descriptive naming for "FAR" and "DFSC". Don't print ISS twice. Shift IL value so it's printed as 0x0 or 0x1, not 0x2000000. Example before: secure os: data fault: PC at 0x1edb87901778(0x19778), FAR 0x0, iss 0x44 secure os: load bias: 0x1edb878e8000 secure os: ESR 0x92000044: ec 0x24, il 0x2000000, iss 0x44 after: secure os: data fault writing to 0x0, PC at 0x1edb87901778(0x19778) secure os: fault code 0x4: Translation fault, level 0 secure os: load bias: 0x1edb878e8000 secure os: ESR 0x92000044: ec 0x24, il 0x1, iss 0x44 Change-Id: I4922328373e13443c999c2c79ea0ba2606417aeb
The LK embedded kernel. An SMP-aware kernel designed for small systems.
See https://github.com/littlekernel/lk for the latest version.
See https://github.com/littlekernel/lk/wiki for documentation.
This will get you a interactive prompt into LK which is running in qemu arm machine ‘virt’ emulation. type ‘help’ for commands.
note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
